ZBOTTLE-CBPPING MACHINE.

Specicetion of Letters Patent.

. Application led may 4,

To all whom zt may concern:

Be it known that L'ANDY P. LUNDEEN, a citizen of the United States, and a resident of Galesburg, iu the county of Knox and State of Illinois, have invented a new and' useful Bottle- Capping Machine, of which the following is a specification. My invention relates to machines for inserting paper or similar caps in milk-bottles and the like. l'

One of the objects of the invention is. to provide a relatively inexpensive machine the price of which will not beaprohibitive to the small dairies.

Another object is to pr vide novel means for feeding the caps successioually tothe cappin mechanism.

Anot er object is to provide novel capping mechanism operating conjointly with the feeding mechanism.

Another object consists in providing novel structural features.

Still another object consists in making thev machine etiicient in use with bottles differing in height.

Concisely stated, the object principal end and to `the invention 'is to generally improve the construction and increase the capacity, utility and etliciency of devices of this character, and it consists, substantially, in the improvements herein shown and escribed.

In the accompanying drawings, which illustrate my invention as embodied in the best Way now known to me, and which embodiment has been successful in practical operation: l

Figure 1 is a side elevation showing the device in position to start to operate in capping a milk-bottle;

Fig. 2, a similar view, but showing the operation as having been completed;v

Fig. 3, a rear elevation, the parts in the same relative positions as in Fig. 1;

Fig. 4, a top plan, illustratinor by dotted lines the movement of the capceder; and

Fig, 5, a vertical section, its plane taken I in the line 5--5 in Fig. 4.

Coming now to a detailed description of the drawings, and indicating the elements and, where necessary, the parts thereof each by a distinguishing reference inimerahuniformly employe 2 indicates a table on which the foot 3 of a supporting-leg 4 is secured by n. bolt 5 and nut The leg si terminal of Patented Mar. 19, 1918. 1917. serial No. 166,354.

7 in which reciprocates :i pair of guide-lugs S projecting from the rear of face of the vertical arm o an L- sliapcd bracket 9. A bolt 10 passes through an aperture (which it fits) in said arin and through saidslot 7 and is adjustably secured tothe leg 4 by a wing-nut 11. operating lever 12 passes through a slot 13 in the bracket and is fulcrumed therein by means of a bolt 14 secured in place by a cotter l-see Figs. 1 and 3. For convenience the vertical arm of the bracket is designated by 9, and the horizontal arm by 9". The the arm 9 is formed into a bearing has an elongated slot 16 in which reciproiinged at its enlarged, forked upper end, by means of a pin 16', to the lever 12. Suitably secured to its lower end is a .capping-head 18 having a stem 19. rThe lower end of a compression .or lever-return spring 20, which embraces the plunger, rests on the eye 16 and its upper bears against a washer 21 which rests beneath the enlarged lupper end of thc plunguidc-cye or cates a plunger 17 ger.

The device hereinbefore described may be eiciently operated as a. bottle-capping device, the caps being each fed by hand, or manually. ln using it, a bottle 22 is placed in proper position, as shown, and a cap 23 laid in the upper portion of its mouth. Upon operating the lever 12 the plunger 17 will be forced down to thereby drive the head 18 onto the 'cap 23, and a completion of the throw of the lever will force the cap onto its seat 2-l in the neck of the bottle. Upon release of the lever the spring 20 will return it and also head to their normal positions, ready for another operation.l

25 indicates a cap-holding cylinder secured to the bracket-arm 9 by a clip 26 or in any other desire-d manner. lts bottom is formed by a pair of substantially quadrant shaped pieces 27 spaced from each other to provide a way 28. The front half, or thereabo'ut, of the lower end of the cylinder is open, as indicated at 29. Fig. 4. On the out-er lower edge of the cylinder is a capguidiiig tongue 30 which consists of a strip of sheet metal preferably soldered at one of its ends to the cylinder. its other end projecting slightly past the part 31 now to be described. v

3l designates the upper portion of the botthe plunger and capping soldering, to the lsides 31 jecting from one of l an carry it to -66 and each reciprocable in re brackets 38 secured to the stem 19 by screw-'- relief-springs,

.move relatively outward to toni of an inclined chute'the lower portion 32 of which has a less degree of inclination. 33 indicates a bottle-neck guide-ring having an annular flange 34.. At its rear portion said ring is provided with a cap-guiding projection 435 which yis soldered to thelower terminal of the part 32. The projection 35 consists preferably of. a small piece of sheet;

metal, transversely curved, the free edge ofwhich overlies t flange 34 and the l ably soldered to the cheeks of the element 32. 36 indicates a guard suitably secured, as by of the chute bottom 31. l37, 37 indicate guide-rods each fixed at its lower end to the guide-ring 33 e adjacent edge of the bolts 39. 40, 40 designate each embracing one of said rods 37, the uper end of each resting against the lower ace of the upper eye of the adjacent bracket 38 and its lower endon a cross-pin 41 projected transversely through a rod 37, as

shown best in Fig. 2.

Secured by a bolt 42 to the bracket-arm 9" is a guide-bracket 43 having perforated upturned terminals 44, 45, 46. 47' indicates a bar reciprocatory in said eyes. One of its end'l portions is "directed transversely and thence forwardly to form a ca -pickin' end, 49, i)

finger 48 and the other s turne laterallyvto engage a slot 50 in the ower arin 51 of a bell-crank lever fulcrume at 52 to a supporting arm 53 fixed by a' screwbolt 54 to the arm 9". 55 indicates a pin prothe brackets 38 and eX- tendin through a slot- 56 in the arm 57 of the be -crank lever.

` Preferably a weight 58 orsome other means is used to bear upon the caps in the cylinder 25, not only in order that they may feed properly but also to prevent them from warping and becoming saucer shaped.

The operation is illustrated best in Figs. 1 and 2. As the lever 12 is plunger 17 and head ously depressed, as hereinbefore described,

a cap, previously placed in the bottlemouth, will be pressed down onto its seat, also 'as before described. Upon release of in Fig. 2 to those shown in 55 causing the bell-'crank lever arm 51 to thereby draw upon the terminal 49 of the rod 47, thus .causing the linger 48 'to move in the saine direction, and in so moving itwill draw with it'the bottom one of thecaps 23 in the cylinder 25. The cap will be guided by the tongue 30 and the progressively-stepped chute 31, 32' and 35, and .its momentum will proper position to be operated upon. x Upon actuation of the lever the cap of the sudden stop.

ring flange 34 will befoiced down/to rest lightly upon the .top of the' neck of the bottle, Lne relief springs 40 absorbing the force lunger will, due t e lever 12, continue in its downward movement, forcing the ca firmly onto'its seat. There will be no su den impact,however, for vthe relativlly strong resistance spring 20 prevents suc v Adjustments of the bracket 9 by means of the bolt 10 and wing-nut 11 may be quickly made to accommodate bottles differing materially in. their heights, as, for instance, pints, quarts and half-gallons. Slight differences, such as frequently occur in bottles having the same capacity, are immaterial.
